16 PF CORRELATES OF LOCUS OF CONTROL'
KEITH W . JACOBS Loyola University
In an attempt to further define the personality dimensions of internal and external locuses of control, Rotter's I-E Scale (Rotter, 1966) and Form C of Cattell's Sixteen Personality Factor Questionnaire (Cattell, et al., 1970) were administered to 200 undergraduate college students (84 male, 116 female, mean age 21.64 yr.). The 16 PF was scored for the 16 primary source traits, four second-stratum traits, and five published criterion scores, using combined malefemale college norms for each scale. The obtained mean sten scores for the 16 PF scales ranged between 4.40 and 6.08 (mean of scale means = 5.45, mean of scale standard deviations = 1.87), with a mean Rotter score of 11.71 (SD = 4.67). Similar means and correlations were found for both males and females, all of which appeared very similar to the norms on which the instruments were based. The 16 P F variables significantly but modestly related to Rotter's I-E scores and the zero-order correlations were: ego strengch/C = --.29, protension/L = .24, guilt proneness/O = .34, self conflict/Q2 = -32, ergic tension/Q4 = .43, anxiety second-stratum trait = .48, psychoticism index = .21, neuroticism index = .37, leadership criterion = -.35, and scholastic aptitude criterion = -.34. These small correlations suggest that the individual who feels that he lacks control over his environment tends to score higher on the neuroticismpsychoticism dimensions while the more internally controlled individual is more Likely to have academic and leadership traits.
